BACKGROUND
1. Field

The present invention relates to a chassis system of a remote control vehicle. Particularly, the present invention relates to a chassis system that is replaceable and can effectively reduce the resistance in water for an amphibious remote control vehicle.

2. Description of the Related Art

Nowadays, in some of the conventional chassis systems of amphibious remote control vehicles, an inflatable floating device made of an elastic material is usually coupled to the body thereof to provide sufficient buoyancy to the vehicle while traveling on water, so it is necessary to inject gas into such device. However, with this design, even if the inflatable floating device gets slightly damaged, the vehicle may not be able to stably travel on water.

In some other chassis devices of amphibious remote control vehicles, multiple grid boxes are connected to each other to form a box structure and coupled to the chassis of the vehicle. The box structure may further be filled with a foaming material or an air bag to provide additional buoyancy which is required for the vehicle to travel on water. However, due to the excessive resistance in water results from the excessive volume of the number of boxes and the required connection structure thereof, the vehicle may still not be able to stably travel on water and further causes greater energy consumption.

For the purpose of improving the drawbacks of the prior art, the inventor of the present invention provides a chassis system of amphibious remote control vehicle.
